I think we've mentioned this a few times now.... a pic of just the dial is a bit lacking if you want help. A GOOD CLEAR sizable photo of the case back (both sides) and the movement will help considerably.
Edit... i see now that this is one you bought on eBay since you have used the eBay photo. Case back photo isn't of much help either but its a watch consistent with what Junghans put out in the very late 1940's thru early/mid 1950s and likely has a 93 series movement inside. There is probably not much else to learn about this particular watch other than confirmed the movement and any markings on the inside of the case back.
